Effects of low charge injection densities on corrosion responses of pulsed 316LVM stainless steel electrodes [functional neuromuscular stimulation]

The safe charge injection density for pulsing of 316LVM electrodes has been reported to be 40 /spl mu/C/cm/sup 2/. However, only 20 /spl mu/C/cm/sup 2/ is available for nonfaradic charge transfer and double layer charge injection. Therefore, the authors evaluated long term pulsing at 20 /spl mu/C/cm/sup 2/ with capacitor coupling.
